I've created a custom homemade docker image containing the vhosts configuration, how can I define variables like ServerName
, DocumentRoot
in an ENV when running the container.
Thanks, really appreciate to all answers

You can use the ${APACHE_DOCUMENT_ROOT}
notation in the Apache config file.
I took the example from this unanswered question:
<VirtualHost _default_:80>
ServerSignature Off
ErrorLog ${APACHE_LOG_DIR}/000-default-error.log
CustomLog ${APACHE_LOG_DIR}/000-default-access.log combined
DocumentRoot ${APACHE_DOCUMENT_ROOT}
<Directory ${APACHE_DOCUMENT_ROOT}>
Options FollowSymLinks
AllowOverride all
Require all granted
</Directory>
</VirtualHost>
A very basic Dockerfile:
FROM httpd:2.4
COPY *.conf /usr/local/apache2/conf/
Then I started the built container:
mkdir {log,htdocs}
echo "hi" > htdocs/index.html
docker run -d --rm
-e APACHE_LOG_DIR=/var/log/apache2 \
-e APACHE_DOCUMENT_ROOT=/var/www/htdocs/
-v $PWD/htdocs:/var/www/htdocs
-v $PWD/log:/var/log/apache2/
-P httpd:test
And it works.
$ curl http://localhost:32768/
hi
$ ls -l log/
total 4
-rw-r--r-- 1 root root 85 Oct 7 15:06 000-default-access.log
-rw-r--r-- 1 root root 0 Oct 7 15:05 000-default-error.log
